Automatic centering clamping device for workpiece internal cylindrical surface

Abstract

The invention provides an automatic centering and clamping device for the inner cylindrical surface of a workpiece, belonging to the technical field of machining. It includes a left connecting rod, a right connecting rod and a sleeve. The lower end of the left swing seat of the left centering and clamping assembly is hinged on the left bracket, and the left pressure block is installed in the left support groove of the left swing seat through the left positioning pin. The right pressure block of the centering clamping assembly is installed in the right support groove of the right swing seat through the right positioning pin, the sleeve can be slid up and down on the support section of the driving rod, and the spring support ring is installed on the connecting section of the driving rod. The upper end of the compression spring is fitted with the lower end face of the sleeve, the lower end is fitted with the spring support ring, one end of the left link is hinged with the left support lug, the other end of the left link is hinged with the right middle section of the left swing seat, and the right link is hinged. One end of the rod is hinged with the right lug, and the other end of the right link is hinged with the middle section of the left end of the right swing seat. The invention realizes the automatic centering and clamping of the inner cylindrical surface of the workpiece, and has not only reasonable structure, low cost, but also convenient disassembly.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an automatic centering clamping device for the inner cylindrical surface of a workpiece. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The machinery required for processing consists of digital display milling machine, digital display forming grinder, digital display lathe, EDM machine, universal grinding machine, machining center, drilling machine, laser welding, fast wire walking, medium wire walking, slow wire walking, outer cylindrical grinder, inner circle Grinding machines, precision lathes, etc. Cutting processing refers to the processing method of using cutting tools (including cutting tools, grinding tools and abrasives) to cut off the excess material layer ...

AI Technical Summary

Problems solved by technology

In mechanical processing, many workpieces are centered and clamped through the inner cylindrical surface, such as sleeve workpieces, disc workpieces, etc. At present, the positioning and clamping of many sleeve workpieces and disc workpieces are achieved by air The centering and clamping effect is ideal, so it is widely used, but these structures are more complicated, the production cost is higher, the maintenance is inconvenient, and the service life is short
